Based on a species Presence-Absence matrix including
variables of interest (see `lets.addvar`

), the
function divides a continuous variable into classes and counts
the frequency of each class within each species' range.

1 | ```
lets.classvar(x, groups = "default", pos, xy)
``` |

`x` |
Presence-absence |

`groups` |
The number of classes into which the variable will be divided.
Default calculates the number of classes as the
default for a histogram ( |

`pos` |
Column number containing the variable of interest. |

`xy` |
Logical, if |

A `matrix`

with species in the rows and the variable's
classes in the columns.
